Abstract

La présente invention concerne un dispositif électronique et un procédé de chauffage de batterie, qui se rapportent au domaine des batteries et sont utilisés pour se servir des composants existants d'un dispositif électronique afin de chauffer une batterie sans coûts supplémentaires. L'invention concerne également un dispositif électronique, comprenant : au moins un processeur, un composant de conduction de chaleur, une bobine de charge sans fil et une batterie. Le composant de conduction de chaleur est au moins fixé à la batterie et à la bobine de charge sans fil. Lorsque le dispositif électronique est connecté à un dispositif de charge, l'un ou les processeurs acquièrent des informations de température, et lorsque ces informations sont inférieures à un seuil prédéfini, l'un ou les processeurs fournissent un premier signal de tension à la bobine de charge sans fil de façon à augmenter la température de celle-ci ; et le composant de conduction de chaleur transfère la chaleur de la bobine de charge sans fil à la batterie.
